sh: Fixup r7780rp pata_platform for devres conversion.
Tidy up the R7780RP I/O mapping routines and switch the pata_platform resources to IORESOURCE_MEM types, killing off the useless port->addr conversion. This fixes up R7780RP to boot after the recent devres conversion. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
